PICKit 2 as logic analyzer, 6th AUX pin

[sairfan1]

hi,

i have copy of PICKit2, i want to use it as logic analyzer. I can see logic on pin 4 (PGC) and pin 5 (PGC) as analyzer channel 1 and 2 but there is no pin 6 (AUX) this pin is also used as channel 3 for logic analyzer,

my question is how can i update my pickit2 so that i can use channel 3 also, i have copy of pickit2 having PIC18F2550 on it, and i do not have schematic for this. thanks.

PICkit3 was easy for me to find. View the readme to get dotNet4.0

Hi,

If you download the Microchips PK2 User Guide it has the full circuit diagram in there.

You will have to have a diagram of your 'clone' to compare against it so you can see what the differences are.

It probably is just a missing connection on the clone, as the firmware in the 2550 is usually Microchips.
Probably all you need is to connect pin6 to the 2550 via a 47r resistor..... ?

thanks, i m trying to find out pins, will get back when solved.

I added 33ohm resistor from PIN 6 of MCU (RA4) to PIN 6 of jack (AUX), and one 10k resistor pull down, and its working fine, thanks.
